The evasive Claw

[TimewasterOG]

Hey folks! Hoping you can help me pin down why 1 plant out of my tent is having clawed leaves pretty severely and the rest are not. Background: all in 1 part kryptonite soil blended with 1 part sunshine mix and .5 worm castings - added 3/4 dose of blood meal at the beginning (wondering if this could be my issue), 1/2 dose of gaia green power bloom, insect frass, and some extra myco ….this was in the original mix in the 2 gal fabric pots they started in. I potted up to 5gal fabric pots and did not add more blood meal but did supplement with more power bloom and a bit more insect frass. Have been light feeding with liquid seaweed (2-2-7), calmag, fulvic acid and some fish juice through veg. I’m thinking the blood meal would be more than done after 10 weeks of veg and repotting and all other dry amendments were not full strength so I’m wondering how I could have managed to give her too much n - what makes me unsure is her sister is same strain, same treatment, same nutes- no clawing. The one with the claw is in a corner of the tent where my oscillating fan stops and turns back - should I try moving positions….could it be too much wind? Shouldn’t be too much light - I have a 510 eco farm z set up now about 12” + from canopy, which is an upgrade from a spider farmer 2000 / 600hps combo, and she is in a corner so not getting all of it. I’m stumped and going to try a flush on her when dry. Could I have failed to mix the dry amendments well enough and she ended up with extra in her pot? Here are some photos. Tossed in a couple of my NL auto just for fun (first time with autos and I might’ve been heavy with the nutes on her too). Thanks for any suggestions!

ps…tested run off water from flush I just completed (7.5gal seems like a LOT to put through a 5 gal pot!) came out at 6-6.5 (only have the vial and drops - hard to be exact). Tried to do a slurry but couldn’t see a colour change. But doesn’t seem like it’s a ph issue based on that (assuming run off is a half ass accurate way to test)

Day/night temps? Do you monitor soil temp?

I've never used that soil before, but it says it's all you need from veg-harvest, so I'm guessing it has a lot amendments. So yeah, you got it right, I'm sure the added blood meal and gaia green caused the N overdose. Next time, let the soil ride until you see signs you need to add something else. I would skip the blood meal in the future, it's too hot, lots of better alternatives for N, like alfalfa or fish hydrolysate.

I will 2nd Rurumo.

You maybe are complicating your grow by amending and then feeding liquid nutes too. It makes it hard to discern what is causing issues. If you only gave it GG, for example, it would be much easier to deal with toxicity and the like.

I wasn’t buying the “all you need” for the whole run line from that soil. But you’re right, I should’ve held off on the blood meal for sure - I just figured they’d use it up during veg cause I vegged so long and be ready for flower by the time it was used. Will save the blood meal for outside gardens. So you’re thinking it’s nute related and not wind?

Thanks man! I have read this one (along with several others). One thing I failed to mention is as I left off with the liquid nutes on this lady for the last like 4 feedings and she’s not improving. That combined with the fact she is the only one showing the claw makes me think it might be something else

You are absolutely right! I did fail to mention I stopped with the liquid nutes when I noticed the claw starting on this one, just water and one dose of fulvic acid to help with nute uptake. But she is still clawing in the new growth. Time to try a flush with just water? 1.5x the volume of container should do? I’m also going to move things around to see if it is wind related. The fact she is the only one and the same strain right beside her totally happy has me scratching my head - why would it just be her??

Day/night temps? Do you monitor soil temp?

Good question! I totally missed that part. Was having some temp control issues (is why the NL auto is all taco’d) but that was before the claw started and I got my exhaust fan set up. Now day is 23-26 c/50-60% rh and night gets down to 21 c and humidity stays around same. I have no way to measure soil temp but have dropped the sensor down to the pots and temps stay pretty close (maybe a bit cooler) so I’d have to think soil temps are in that range too. The other possibility is ph issues - but why only her?? Will make a slurry to test when lights come on to get an idea (I have no gear for ph except for the drops)

UPDATE: Can’t fix it.
I forgot to mention the strain is Fizzy Peach from holy smoke seeds (amazing selection of genetics! Shameless plug for them) I’ve flushed late last week, then a very light flower nute (biocanna flores + boost at 25% strength) when she dried. Then a heavy water with some volcanic dust topdressed with some more myco (**she did get too dry before this started- could I have killed off my soil bacteria??). Still no improvement. Last water I tried 50% strength fulvic acid and calmag. Still no improvement. New growth is definitely lighter green now, and tops are slightly less clawed (but inside growth is worse - see photos). Going to stop adding anything and just go with water from here for this one I think.
So it’s been fairly humid here and I’ve been struggling to keep the rh under 60 since I started flower and the day temps are up around 26 - a little higher than I’d like. Could high(ish) temps and high humidity be contributing to this? She was also in a corner where the oscillating fan stopped and turned (a problem I saw someone else have in my reading) so I moved her…but no improvement. Also, I have a key lime pie dosido also in a direction change corner and she is happy as can be. Absolutely stumped how to fix her. Should I try repotting? I Noticed what might have been mildew growth in inside fabric pot the other day- could I be having root problems?? They’re definitely thick in there- have a hard time getting my finger in to check soil wetness. Last question: also have a fan on the floor - could I be overblowing on the roots? Making them too cold or over air pruning? Searching for any answers at this point

 

[TimewasterOG]

Here is her sister- same strain, right next to her. None of the issue. Baffled - it would make more sense if more of them were showing symptoms (but that is a bright side at the same time). Thanks again for any advice

From my view, the list of stuff you tried is a crazy long list of things.

When things arent going well and you suspect an overdose of any nutes, watering them down, so to speak, flush, water only etc. is typically what is done.

I don't think you realize the timing of things. What you add to the soil...or whatever you do today to a soil grow, takes at least 4 or 5 days to have the change register. If topdressing it can take 10 days or more.

So every time you try something different, it further confuses the situation.

Each plant, even if the same strain, can respond differently.

So if one plant show N toxic, it needs to be dealt with separately. If they all show it, you can handle it similarly.

Change one thing at a time, and observe. If the N toxicity did not go away, you obv havent gotten it out yet.

You need to slow down your thinking a bit, not panic, focus....

And only act when you are almost sure what to do. In any other case, don't change anything.

--------

When I look at the original pics, I do see a lot of N. The only thing I would have changed is to do everything the same EXCEPT make sure no more N goes in.

If you stop your brain from thinking EMERGENCY and instead calmly think, needs an adjustment, the feel of it will change.

I was where you were in my first grow. A higher power than us controls how things grow. You can harness it, learn how it works, and unlock the secrets by being an observer.

You have a nice grow going, I think you are overreacting to a mild issue.

I am feeling pretty good about it except for this issue I can’t pin down. And you’re right - I have a tendency to over complicate things for sure. Will go with just water for st least a week or 2 and see how things go. In my defence I did give a good 5 days after the flush before moving into trying other things when she didn’t turn around. And really those other things are things I would have done anyway if she hadn’t gone all weird , just in lower amounts. I do appreciate the feedback though and really will try to keep things less complicated

5 days wasnt enough. It is that simple.

Perhaps the soil wasn’t mixed properly and this particular plant got a chunk of blood meal?

It can be tricky to mix evenly. Only thing that I can see.

That’s the thing! I only added blood meal at 3/4 strength at the very beginning for the soil in the 2 gal pots they started in. Even if that pot had excess it would be used up by now and I’ve repotted since then (quite some time ago)- that’s one of the things has me stumped. It must have something to do with getting too dry that one time (left it too long and started to droop). The highest N content in this soil was gaia green insect frass (3-2-4 I think, not sure) and that was a while ago so I can’t figure why she would have so much n

Oh right yes. Drying the media out concentrates the nutrients. That could be a factor.

Also they are time release right? Problem is it’s a guessing game as to when they are releasing? Perhaps one is finished while the other is just breaking down?

It suggests reapplying the bone meal every 4-6 weeks so after 3+ months it HAS do be done, no? Perhaps she’s just more sensitive. My first run with this strain so I’m learning

There is some clawing but its not bad yet, maybe ease up on nutes for a while, maybe 1/2 dose. Fourth pic in your original post shows leaf canoeing and slight burning on leaf edges. I'd look at raising light 8-10".

Really? You wouldn’t consider that an advanced case of clawing?? And yes, that NL auto got burned a bit - heat and nutes both I think. Had difficulty with climate earlier in summer - hard to fight 40 odd degrees outside. She’s just about done now though
